COP404C ROMless CMOS Microcontrollers
General Description
The COP404C ROMless Microcontroller is a member of the
COPS
TM
family, fabricated using double-poly, silicon gate
CMOS (microCMOS) technology. The COP404C contains
CPU, RAM, I/O and is identical to a COP444C device ex-
cept the ROM has been removed and pins have been add-
ed to output the ROM address and to input the ROM data.
The COP404C can be configured, by means of external
pins, to function as a COP444C, a COP424C, or a
COP410C. Pins have been added to allow the user to select
the various functional options that are available on the fami-
ly of mask-programmed CMOS parts. The COP404C is pri-
marily intended for use in the development and debug of a
COP program for the COP444C/445C, COP424C/425C,
and COP410C/411C devices prior to masking the final part.
The COP404C is also appropriate in low volume applica-
tions or when the program might be changing.
